In this paper, an efficient residue to binary converter design for the new high dynamic range moduli set {2-1,2+1,2,2+1,2-1} is presented. The reverse conversion in the four-moduli set {2, 2+1, 2+1, 2-1} has been proposed in literature. Hence, the converters are based on the new moduli set {2-1, (2-1)(2+1)(2+1)2} and propose its residue to binary converter using New Chinese Remainder Theorem 2 ...

Tone Mapping Operators (TMOs) compress High Dynamic Range (HDR) contents to address Low Dynamic Range (LDR) displays. While many solutions have been designed over the last decade, only few of them can cope with video sequences. Indeed, these TMOs tone map each frame of a video sequence separately, which results in temporal incoherency. Two main types of temporal incoherency are usually consider...

The high dynamic range of illumination may cause serious distortions and problems in the view and further processing of digital images. In this paper a new fuzzy based tone reproduction pre-processing algorithm is introduced which may help in developing the hardly or non viewable features and content of the images making easier the further processing.

Experiments at storage ring light sources as well as at next-generation light sources increasingly require detectors capable of high dynamic range operation, combining low-noise detection of single photons with large pixel well depth. XFEL sources in particular provide pulse intensities sufficiently high that a purely photon-counting approach is impractical. The High Dynamic Range Pixel Array D...

The presentation discusses the requirements on the characteristics of antenna and RFsubsystem of a FMCW Imaging Radar with respect to the dynamic range and presents the design of an advanced demonstrator. The discussion is based on experience with the HiVision-Radar system /1/ which observes the ground from an elevated position (e.g. airborne platform, see also /2/) and employs a frequency scan...

Here, we report results from psychophysical experiments aimed to assess the performance of the Samsung OLED display as contrasted to that of a typical LCD display in the context of high-dynamic range (HDR) image rendering. Our test scenes depict ”blobbie” objects embedded in an environment that contains regions with strong shadows. In the assessments described here we examined 8 variations of t...

High Dynamic Range (HDR) imaging is one of the technologies that are changing photo, TV, and film industries. The popularity and full public adoption of HDR content is however hindered by the lack of standards in evaluation of quality, file formats, and compression, as well as large legacy base of Low Dynamic Range (LDR) displays that are unable to render HDR. Many tone-mapping operators, aimin...

An algorithm for blending multiple-exposure images of a scene into an image with maximum information content is introduced. The algorithm partitions the image domain into subimages and for each subimage selects the image that contains the most information about the subimage. The selected images are then blended together using monotonically decreasing blending functions that are centered at the ...

The real world consists of many scenes which contain a high dynamic range. While modern cameras are capable of capturing the dynamic range of these scenes, displays still only show a low dynamic range. Many tone map operators exist but very few consider the use of head-mounted displays. We create a dynamic tone map operator for use on panorama high dynamic range images by considering a user’s h...

The main objective of this paper is to verify test methodologies for the assessment of high dynamic range (HDR) video. To achieve this, a next generation HDR monitor by Dolby Laboratories was used to display professionally produced HDR content. Two complementary approaches for subjective assessment of HDR video were then designed and carried out at the European Broadcast Union and Ecole Polytec...
